SEEDER ATTACHMENT FOR GULTIVATORS.

., Specification of Letters Patent.

Patented Aug. 31, 1915.

Application filed July 18, 191%. v Serial No. 351,778.

To all whom it may concern:

Be it known that L CHARLES A. RUTHER- noun, a citizen of the United States, residing at Kaw, in the county of Kay and State of Oklahoma, have invented certain new and useful Improvements in Seeder Attachments for Cultivators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in attachments for cultivators and more particularly to a seeder attachment for corn, peas and any suitable gram which can be used-in a cornplanter, the main object of the present invention being the provision of l a planting attachment;

which can be readily applied to a cultivator or removed therefrom and which is actuated through means attached to one of the cultivator wheels. 1.

Another object of the pi esent-inventlon is the provision of a cultivator attachment of the above character which 'will possess ad vantages in points of efficiency and durability, isinexpensive to manufacture and,

I at the same time, 1s simple in construction and operation.

With the above and other objects in view, the invention ,consists in the novelfeatures of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed outin the specification and claim.

In the accompanying drawings forming a part of this application, Figure 1 is ,a'rear elevation illustrating a planter attachment constructed in accordance with my invention. Fig. 2 is a side elevation. Fig. 3 is a top plan view; Fig. 4 is a bottom plan view.

Fig. 5 is a. detail transverse sectional view. Fig. 6 is a plan view of the rotatable plate. Fig. 7 is a transverse sectional view through the operating shaft illustrating the mounting of the sliding sleeve. 8 is a side elevation of the clamping bolts used to fasten thesprocket to the cultivator wheel; and Fig. 9 is a side elevation of one of the yieldable tongues illustrating the mounting of the same.

Referring more particularly to the drawings, indicates a cultivator frame, and 2 indicates the axle supporting the same, the ends of which are bent downwardly and disposed in a vertical position, as shown at 3 and their extreme ends bent at right angles to the vertical portions 3 to form spindles,

the supporting wheels 4: are

, to receive a portion of the vertical member 3 which is securely held in position by means of the clamping block 7. The body 5 of the attachment is provided with a central opening 8 which is preferably threaded upon its interior, the purpose of which will be hereinafter more fully set forth. Rotatably mounted within the body is a plate 9 having a series of openings 10 formed therein which are adapted to register with a similar opening 11 formed in the bottom of the body 5, i

whereby the corn, peas or other grain may pass ,therethrough and into the hopper 12 and from thence into the boot 1.3. In order to securely retain the plate 8 in its operative position, I provide a casting 14 which is mounted within the upper portion of the body and securely held in position by means of a wing nut 15 having a screw 16 formed integral therewith and adapted to extend through the center of the casting and extend through the opening 8.

Pivotally mounted within a portion of the casting 14 are the yieldable tongues 17 the inner ends ofwhich bear upon the coil spring 18, so as to yie'ldably retain the outer ends thereof into engagement with the rotatable plate 9. These tongues are incloscd and securely held in place by means of a cover 19 which is preferably of a design to entirely inclose the tongues and is securely held in position by means of a bolt 20 which extends through the casting 1e and through Projecting downwardly. from the bottom of the body 5, are the spaced bearings 26 ar-jj ranged at diametrically opposite points upon to p the lower side of the body and mounted.

I for rotation therein, is a shaft 27 upon one end of which is mounted a sprocket 28, around which is adapted to extend a chain 29, said chain extending around a second sprocket 30 which is supported upon the inner side of one of the wheels 4. lhe sprocket .30 is securely held in position by means of the hook bolts 3]., the threaded ends of which are arranged within suitable openings in the sprocket wheels, while the hooked ends thereof are engaged with the spokes of the wheel 4, whereby the tightening of'the nuts carried by said bolts will clamp the sprocket securely to the wheel. Mounted upon the shaft 27 and arranged in spaced relation with the sprocket 28, is a bevel gear 32 which is adapted to mesh with the annular gear 33 formed upon the inner face of the plate 9', whereby the rotary movement of the shaft 27 will actuate the gear and rotate the plate 9 within the body 5.

Formed integral with the sleeve 34 having a clutch face 35 adapted to engage with the clutch face formed upon the movable sleeve 36. The sleeve 36 is provided with an elongated opening 37 adapted to receive a lug 38 formed upon the shaft 27 whereby to prevent rotary movement of the sleeve with respect to the shaft. Thus, when the'clutch faces of the two sleeves 34 and 36 are engaged, the sleeve 36 is provided upon its end opposite the clutch face with an annular flange 39, the purpose of which will be hereinafter more fully set forth. Pivotally connected to the lug 40, at one side of the body 5, is a lever 41 which extends transversely across the bottom of the body and is movable within a rack 42 which is suspended from the lower end of the body and is provided with a plurality of teeth 43 which are adapted to be engaged by a spring actuated catch 44 to retain the lever in various adjusted positions.

. A U-shaped member 45 is carried by the lever and is adapted to engage-with the flange 39 of the sleeve 36 to move the sleeve longitudinally upon the shaft 27 and engage or disengage. the clutch members whereby the operating mechanism may be drawn into or out of engagement with the driving mechanism. From this it will be apparent that i upon inward movement of the sleeve 36, the

; clutch faces will be disengaged so as to dis connect the planting mechanism from the driving mechanism, but when it is desired to gear 32 is a my improved planter may be quickly and readily attached to various forms of cultivators and, at the sametime it is extremely simple in construction and can be manufactured and placed upon the market at a com-' paratively low cost.

While I have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying my invention'into practice, without, sacrificingany of the novel features or departing from the scope of the invention, as defined by the appended claim.

Having thus described this invention, what I claim is 4 v A device of the class described including a body, a plate mounted for rotation therein, a casting carried by the plate, yieldable tongues mounted within said casting, a coil spring disposed between the inner ends of each of the tongues and the casting, and the outer ends of said tongues engaging the rotatable plate, an annular gear formed on the lower face of the plate contiguous with?- the edge thereof, an operating shaft extending across the lower face of the body, a gear loosely mounted thereon adapted to engage with the annular gear, a clutchcarried by the second gear, a second clutch movable upon the shaft, means carried by the shaft CHARLES A.
